Series | iio: adc: ad7292: remove unneeded spi_set_drvdata() | expand |
LGTM. Tested on raspberry pi kernel - rpi-5.9.y. ad7292 was heavily based on ad7768-1. Maybe this might apply to ad7768-1 as well.

This seems to have been copied from a driver that calls spi_set_drvdata() but doesn't call spi_get_drvdata(). Setting a private object on the SPI device's object isn't necessary if it won't be accessed. This change removes the spi_set_drvdata() call.
